Another interesting stat I found along the way was more children were receiving free or reduced lunch than not even prior to the pandemic.

Very low on the list of reasons it's difficult is the percentage of those just plain not interested in the idea. It may seem silly ("we all agree no kid should go hungry at school so why haven't we done it universally") but picking that one reason out of the hat and holding it out as why isn't helping anything.
When it comes to the resources used by disabled people I think of comments by Nolan Bushnell in a dead tree magazine interview. The interviewer asked him how he deals with unproductive engineers and Nolan says he didn't care about unproductive engineers. Because an unproductive engineer just wastes his salary. What he cared about was negatively productive engineers. And managers especially. What I see is there are a lot of heavily compensated people who destroy value their whole careers. And those people take a far and away bigger share than all the disabled people.
Where this tends to be going is a lot of that guy are the above, highly compensated less than worthless people. consider as you're career progressed up. Maybe when you started working most people around you had lower end jobs and were productive. And as you went up the percentage of people actually pulling their weight went down.
So yes most people doesn't mind people on disability. But the thin upper strata of that guys sure do.
